This is an RF shield made for developing custom RF coil arrays for MRI research. The top half of the shield can be easily separated, allowing easy access to the coil array without moving it. The frame of the shield is made of laser cut 1/4" birch, and the shielding surface is made of common 1/16" copper clad FR4. The conducting surface is segmented and stitched with capacitors so that it shields RF fields, but is transparent to audio-frequency magnetic fields.
